That tips solve me half of problems =DSo, I used the MiniAide Fat32 Formatter program to format my USB pen, and I also notice that the GDI Folder structure was wrong.I needed to put like: "disc.gdi", "track01.bin", "track02.bin", "track..... etc.".Now is working good! One more time thank you for the help =D
